I've seen a lot of death, a lot of pain, a lot of suffering; but I've also seen a lot of life, a lot of beauty, a lot of wonder. It's not the number of years we live that matters, our lives just add up to a series of moments. We never know when or where they'll happen, but they stick with us marking our souls forever. The problem with living 200 years isn't the loneliness or the loss, okay sure it is those things, but what really gets you is when life ceases to surprise you. I've spent my entire life studying the human body, and I can say with scientific certainty, that what keeps us alive more important than blood or oxygen or even love, is hope.
